Configuring IP addresses
3
NOTE
You must set the super-user password before you can set other types of passwords.
4. Enter the following commands to set the port configuration and read-only passwords:
BigIron RX(config)# enable port-config-password <text>
BigIron RX(config)# enable read-only-password <text>
Syntax: enable super-user-password | read-only-password | port-config-password <text>
Passwords can be up to 48 characters long.
Configuring IP addresses
The BigIron RX Series switches implement separate data and control planes. This architecture
affects how you assign IP addresses. Table 14 outlines the interfaces to which you can assign IP
addresses.
In this table, “in band” refers to an interface over which user packets are routed, while “out of
band” refers to an interface over which control packets related to system management are
forwarded.
This section describes the following:
BigIron RX Series support of sub-net masks
How to assign an IP address to a management interface
How to assign an IP address to an interface or virtual interface over which user packets are
routed

Support of sub-net masks

The BigIron RX Series switch supports both classical IP network masks (Class A, B, and C sub-net
masks, and so on) and Classless Interdomain Routing (CIDR) network prefix masks.
To enter a classical network mask, enter the mask in IP address format. For example, enter
“209.157.22.99 255.255.255.0” for an IP address with a Class-C sub-net mask.
To enter a prefix number for a network mask, enter a forward slash ( / ) and the number of bits
in the mask immediately after the IP address. For example, enter “209.157.22.99/24” for an
IP address that has a network mask with 24 significant (“mask”) bits.
